An RSVP Closed Interval; similar to the existing RSVP Interval, except allowing the event creator to close RSVPs at some interval prior to the event start. For example, the organization I’m working with has meetings where they need the attendees list 24 hours ahead of time, and don’t want any stragglers slipping in after that point. Now we can certainly go in and disable RSVPs manually, 24 hours in advance, but between human error and forgetfulness, it would be far more elegant and helpful to be able to set the RSVP deadline when creating the event, and not have to think about it.
